Overview
Join to apply for the
Senior Actuator Design Engineer
role at
Figure . Figure is an AI Robotics company developing a general purpose humanoid. Our humanoid robot, Figure 02, is designed for commercial tasks and the home. We are based in San Jose, CA and require 5 days/week in-office collaboration. It’s time to build. Responsibilities
Own the mechanical design of electric actuators, including lamination stacks, high-speed rotors, geartrains, and bearing systems Design and size planetary gearboxes and other reduction stages to meet torque density, speed, and lifetime requirements Architect full actuator assemblies including structural layout, thermal path considerations, and serviceability Lead design of rotor and stator assemblies including magnet retention (adhesives, interference fits), balancing, and burst strength analysis Perform detailed tolerance stack-ups, shaft fits, bearing life calculations, and structural analysis using FEA Use KISSsoft or Romax to model gearbox performance, lifetime, and manufacturability Develop detailed CAD in CATIA and release complete drawing packages for supplier release and internal manufacturing Collaborate closely with electromagnetic, controls, and system teams to deliver integrated, validated actuator solutions Support vendor discussions and DFM reviews to ensure robust and scalable production of actuator components Requirements
Bachelor’s degree in Mechanical Engineering 3+ years of experience in mechanical design of actuators, electric motors, or gear-driven systems Strong fundamentals in mechanical design, dynamics, and structural analysis Proven experience designing planetary or other compact gearbox architectures Deep understanding of bearing selection, preloading, and life estimation Proficiency with CATIA (V5 or V6) for complex assemblies and surfacing Hands-on experience with rotor balancing and high-speed design for rotating systems Proficient with KISSsoft or Romax for gearbox modeling and optimization Excellent communication skills and ability to thrive in a fast-paced, cross-functional environment Preferred Qualifications
Master’s degree in Mechanical Engineering with a focus on machine design or dynamics Experience designing actuators for robotics, aerospace, or automotive applications Knowledge of thermal management in compact electromechanical systems Familiarity with lamination stack-up design, magnet bonding, and motor assembly methods Experience taking actuator designs from concept through prototyping and into production Compensation
The US base salary range for this full-time position is between $150,000 and $190,000 annually. The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended. Seniority level
